U.S. Enlisted Army Ranks

Enlisted Soldiers are considered the backbone of the Army. They train in a particular job and utilize the skills within their unit. They properly perform their job functions, and their knowledge ensures the success of their unit’s mission within the Army.

Enlisted ranks are broken down into three groups: Junior Enlisted (E-1 through E-4, NCOs (E-4 through E-6), and Senior NCOs (E-7 through E-9). The Army ranks in order for Enlisted Soldiers are as follows:

Private (E-1)

Private is the lowest enlisted rank during basic training. This rank does not carry insignia on the uniform.

Private (E-2)

After completing Basic Combat Training, almost all soldiers receive the rank of Private Second Class. This is the first promotion for the majority of enlisted soldiers after completing basic training, or they will get promoted after serving six months in the Army. The soldier will perform the skills and knowledge acquired in their new job. They will also follow orders from higher-ranking supervisors.

Private First Class (E-3)

Within a year, soldiers will typically be promoted to Private First Class. Soldiers holding this rank are important to this branch. They are known as the backbone and workforce strength of the Army.
